What are the functions of the four major chassis systems?

[KayleeMarie]

The functions of the four major chassis systems are: 1. Transmission system: Transmits the engine's power to the driving wheels; 2. Running system: Supports and installs various component assemblies of the vehicle, transmitting and bearing various loads from both the vehicle and the ground to ensure normal vehicle operation; 3. Steering system: Ensures the vehicle can travel in the direction selected by the driver; 4. Braking system: Enables the vehicle to decelerate, stop, and reliably remain stationary. The maintenance methods for the chassis include: 1. Regularly check the assembly oil; 2. Replace brake pads and clutch plates in a timely manner; 3. Perform four-wheel alignment; 4. Monitor tire pressure conditions—excessive pressure can lead to tire blowouts, while insufficient pressure increases vehicle resistance and fuel consumption; 5. Keep the vehicle clean by regularly washing the car and cleaning the chassis; 6. Protect metal parts exposed to the air; 7. Clean the original paint layer; 8. Avoid wetting the car's floor mats to prevent chassis rust.
